ATTACHMENT FOR CARDING-MLACHINES.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application filed December 24, 1913. Serial No. 808,536.

To all whom it may concern Be it known that I, THOMAS ll-Hnnonn, citizenoi the United States, residing at W inooski, in the county of Chittendenand tate of Vermont, have invented certain new and useful Improvementsin Attachments for Carding-Machines, of which the following is aspecification, reference being bad therein to the accompanying drawing.

My invention relates to improvements in attachments for cardingmachines.

The object of my invention is to provide an attachment for a machine ofthls character adapted to gather the wool-fiber after it has been combedby the dofi'er-comb, and to convey it to 'one side of the machine and vtime partially twist it so that it will be heldtogether in a uniformsliver ready to be presented to the card finisher.

Another object of my invention is to provide a simple, cheap andeffective attachment of this character having certain dei ofconstruction and operation herein- .riioer more fully described.

In the accompanying drawings'Figure 1 showing my attachment appliedthereto. Fig. 2 is a side view of Fi 1, looking in the direction of thearrow 0 Fig. 1. Fig. 3 is an end view of Fig. 2, looking in thedirection of the arrow of Fig. 2. Fig. 4 is a side elevation showing indetail the drawing roll and the rotating tube. Fig. 5 1S :1 verticalsectional view partly broken away and taken on the line A-B of Fig. 1.

Refer-rim now to the drawings, 1 represents the frame of my improvedcarding machine which is provided with the usual dofler-roll 2 and thedofi'er-comb 3, all of which is of the usual structure and needs nofurther description. Secured to the dofi'ercomb 3 is a board l adaptedto convey and keep the fiber down upon the belt carrier 5, as will behereinafter more fully described. Carried by the shaft 6 of thedofier-roll 2 is a sprocket wheel 7, over which passes a chain 8, thesaid chain passe over a sprocket 9 carried by a shaftlt). an said shaftcan ries a stepped pulley 11.

The dotler-comb 3 tion. Below the lower end of the board 4 is a beltcarrier 12 extending the half length of the doffer roll 2, and uponwhich new of a carding machine.

is operated in any desired manner and needs no further descripthe fiberis deposited as it is combed by th doifer comb 8. This belt carrier, asshown in Fig. 2 of the drawing, is of the endless belt type and thepulley 12, over which the belt-carrier passes, is provided with asprocket 13, over which the chain 14 passes.

The said chain extends to the right of the machine and passes over asprocket 15, mounted upon the shaft 16 of the drawingroll 17. Thisdrawing-roll, as shown, is at one side of-the dofier roll 2 and in ahorizontal plane approximately that of the upper face of the endlesscarrier'5. This shaft 16 is driven in the usual manner and needs nofurther description. The rotation of this drawing-roll shaft 17, throughthe medium of the sprockets 13 and 15 and chain 14:, rotates the pulley12 over which the endless conveyor passes, by means of which the same iscaused to deliver and convey the fiber as it is combed from thedofi'er-roll. Below the drawing-roll 17, is a second drawing-roll 18.These rolls are provided with openings 17 and 18 respectively,registering with the opening through which the sliver passes, as willbehereinafter more fully described. Arranged at the right ofthebelt-carrier 5, is a taper-roll 19 having the spiral grooves 20 in itsperiphery and which is adapted to receive the fiber from the beltcarrier and twist and roll the sliver, whereby a knotted or irregular"fiber may be more readily straightened out and gathered before going tothe finisher. The taper-roll 19 is carried by a shaft 21' having apulley 22 over which passes a belt 23, which also passes over the pulley11, and by means of which the taper-roll is continuously driven. At theend of the taper'roll 19 is the rotating tube 24, which is driven by. abelt, 25, which in turn is driven by the same'mechanism that drives theshaft 16 of the drawing roll 17 and needs no further description. Thisrotating tube 24, as shown, is at a point on a line with the beltcarrier adjacent the 100 inner periphery of thetaper-roll, whereby thesliver as it is twisted" by the ta er-roll passes through the rotatingtube. an is ther twisted and passes from this rotating tube between thedrawing-rolls, where it is 105 further compressed and passes from themachine in a comparatively compact sliver, so

that it can be readily handled in presenting it to the finishingmachine.

Having thus described" my invention, 11o

what I claim and desire to secure by Letters Patent is- 1. Thecombination with a carding vInachine, of a carrier below thedofi'er-comb and a taper-roll having spiral grooves adapted to receivethe fiber from the carrier and twist and convey it. to one side-of themachine. w

2..The combination with a carding machine, of an'endless carrier belowthe dofier comb, of a taper-roll having spiral grooves adapted toreceive the fiber from the endless carrier and twist; and convey. it toone side of the machine.- v

of 'a'n endless conveyer below the dolfercomb, a taper-roll havingspiral grooves in its periphery and adapted to receive the fiber fromthe endless conveyor and twist 3. "The combination of a carding machine,

and convey it to the side of the machine,

"and a rotating tube through which the sliver is forced bythe-taper-roll.

The'combination with a carding machine, of an endless conveyer below the'dotl'encomb, a rotating taper-roll having spiral grooves in itsperiphery and adapted to receive the fiber from the endless con-- vey erand twist and convey the fiber-to the side, a rotating tube adjacent theend of the taper-roll and through which the sliver passes, drawing rollsadjacent the rotating tube and between which the sliver passes, andmeans driven by the carding machine 3 operating the endless conveyer,the taperroll, ,the rotating tube and the drawingrolls;

5. chine, a horizontally arranged endless conveyer below the dofler-comban obliquely arranged taper-roll adjacent the end of the endlessconveyer and having spiral grooves in its outeriperiphery, means forrotating the taper roll; and operating the endless Copies of this patentmay be obtained for The combination with a carding ma- -.conveyer, arotating tube adapted to receive the sliver from the taper-roll anddrawingrolls receiving the taper-roll from the rotating tube,substantially as shown and described.

6. The combination with a carding ma-.
